Brief Summary
The goal of this longitudinal observational study is to investigate the pathogen spectrum composition of severe pneumonia (SP) in different disease stages and to study the changes of immune inflammatory factors in patients with SP in different course of disease during and after the COVID-19 pandemic. The main questions it aims to answer is: What is the pathogenic profile of SP patient admitted in intensive care unit (ICU) during and after COVID-19 pandemic? What is the dynamic pattern of etiology and immunoinflammatory factors of SP progression during the period in ICU? Are those indexes mentioned above associated with the prognosis of SP?

Study Arms (1)
Severe pneumonia
Severe pneumonia patients will be continuously recruited in ICU department in Shanghai General Hospital (n=450) and RICU in the First Affiliated Hospital of Chongqing Medical University (n=150) during June 1, 2022 to April 28, 2024. Severe pneumonia was defined as meeting either one major criteria (septic shock with need of vasopressors or respiratory failure requiring mechanical ventilation) or three minor (laboratory and physiologic markers such as uremia or hypothermia) criteria according to the ATS/IDSA major criteria.
Eligibility Criteria
Severe pneumonia patients admitted in ICU department in Shanghai General Hospital and respiratory-specific ICU department in the First Affiliated Hospital of Chongqing Medical University during June 1, 2022 to April 28, 2024.
You may qualify if:
- At least 18 years of age
- Clinical diagnosed of severe pneumonia (case definition: adults according to "Diagnosis and Treatment of Adults with Community-acquired Pneumonia"-- An Official Clinical Practice Guideline of the American Thoracic Society and Infectious Diseases Society of America, 2019)
- Have at least one microbiological test result
You may not qualify if:
- No data of clinical prognosis
